DEVICE FOR ORNAMENTING PAVEMENTS.

SPECIFICATION forming part of Letters Patent No. 519,919, dated May 15,1894.

Application filed May 8,1893. Serial No. 473,373. (No model.)

To all whom it may concern:

Be it known that I, MARTIN MAURER, of the city of St. Louis and State ofMissouri, have invented certain new and useful Improvements inDevicesfor OrnamentingPavements. of which the following is a full, clear, andexact description, reference being bad to the accompanying drawings,forming a part hereof.

Myinvention relates to an improved i tool for ornamenting artificialstone and other forms of pavements dnrin g the process of laying thesame, and consists in the novel construction, combination andarrangement of parts hereinafter specified and designated in the claims.

In the drawings: Figure 1 is a plan View of my improved tool and aportion of a pavement, illustrating the mode of application inornamenting a pavement. Fig. 2 is a sectional side elevation of sametaken on the line A-A of Fig. 1. Fig. 3 is a sectional side elevation ofthe improved tool, with the terminal flanges of the cylinder removed butshown in dotted lines, and with parts broken away. Fig. iisa detailedsection illustrating the manner of mounting the cylinder, with saidcylinder indicated in dotted lines.

The object of my invention is to provide an improved hand-tool forornamenting or laying off artificial stone or other pavements while in aplastic state during the laying thereof, and which tool shall beefficient in operation for such purpose, simple in construction andreasonable in cost. v

By the use of my improved tool I produce simultaneously a large numberof distinct indentations in the plastic material by a single movement ofone of the operators hands in which the tool is held.

Referring again to the drawings, 1 indi cates the main body of the tool,which is preferably in the form of a plain cylinder having squared ends,a smooth outer peripheryand a longitudinal bore 2.

3 indicates a series of separate sections curved transversely to conformto the outer peripheryof the body 1, and having radial meeting edges incontact, so that when all the sections are united and placed in positionupon said body they form a cylindrical shell thereon havingthe definiteconstruction here inafter mentioned. Each of the sections 8 has aconnecting series of projections 4 upon its outer surface, forming adeterminate portion of a definite design, in relief, upon said outersurface, arranged to connect with other definite portions of adjacentsections, and form a complete cylinder with a definite and completedesign upon its outer surface, adapted to indent in a plastic surfacewhen said cylinder is rolled upon the same. Each of the sections 3 hasalso an integral terminal flange 5 in the form of a segment at eachterminal thereof, the same projecting above the outer surface of eachand uniting with the flange of adjacent sections to form completeannular terminal flanges upon the cylinder projecting beyond the outersurface thereof.

6 indicates a spindle which loosely engages in the bore 2 of the body 1and has its opposite ends squared and provided with a threaded bore 7 inwhich islocated a screw 8 having a thread upon its inner portion and aplain outer surface 9.

10 indicates a U-shaped yoke, the arms of which are provided withperforations or bearings 11 which are loosely engaged by the smoothsurface 9 of the screws or bolts 8. Said yoke 10 is thus loosely mountedupon the spindle 6. Loosely mounted upon said spindle between each ofthe arms andthe adjacent end of the body 1 is a washer 12. The completecylinder constructed as above described, is thus loosely mounted torevolve within the yoke 10. A handle 13 has one of its ends secured tothe yoke 10 centrally of the length thereof, by means of a suitale bolt14 and a nut 15, so that said handle projects from the outer surface ofsaid yoke at aright angle thereto.

, The series of sections 3 may be secured in the above describedposition upon the cylindrical body 1 in any known manner, such forinstance as by means of screws or bolts 16 having a threaded innerportion and passed through countersunk openings 17 formed in each ofsaid sections and engaging threaded openings 18 in said body 1, so thatthe heads of said bolts or screws will be flush or below the outersurface of each section.

improved tool, is made of metal and solid, so as to embody as muchWeight as possible, as the Weight of the tool should be such as to I Thebody 1, as well as all the parts of my sink the projections 4 their fulldepth into the plastic compound and bring the smooth intervening spacesupon the outer surface of the sections into contact with the surface ofthe plastic compound.

The operation is as follows: 19 indicates a body of plastic compound,such as plastic pav-.

ing compound, laid upon a suitable foundation 20 of cinders or othermaterial. This material is first providedwith a smooth unbroken uppersurface, and then the improved tool is rolled over this surface while.same is in a plastic condition, by means of the handle, 14 and theprojections 4 will engage" said plastic material and produce upon itssurface. correspondingindentations, and as the forward. movement of thetool continues, a complete and definite designwill thereby be producedupon the plastic compound, the sectional cylinder rolling over and overcontinuously. tion of indenting the design in the plastic compound, theterminahflanges 5' will. produce a straight border line or indentation2lat each margin-a1 edgeof the design thus produced. Likewise,additional designs may be formed in the plastic bodyalongside of andparallel with the previously form-ed design, by placing the annularflange 5 of. one end of the sectional cylinder in engagement withtheseparate border line 21 previously formed. By'proper attention uponthe part of the operator'he may make the succeeding designs mergeintoand correspond with the configurations of the preceding design; soas to form a com-pleteornamental surface upon the plastic body having awidth many times in excess of the length. of the cylindrical.

body 1.

I have found in practice that my improved tool is very efficient in theoperation above described, making with one movement or stroke of thehand a large number of marks or indentations in the plastic material.

I prefer to make the sectional cylinder about one foot in length, so asto retain its size and weight within such bounds that thetool may bereadily handled by a single operator.

It will be seen that this. tool is entirely independent of exteriordevices.

Simultaneously with. the opera- I am aware that prior to my invention aroller formarking designs in artificial stone had been constructed witha marking surface in detachable sections, held in place by ringsthreaded upon the ends of the roller, and I therefore, do not claim suchas my invention.

What I claim is- 1. The improved tool for ornamenting artificialstone,-comprising a main body 1 in the form of a plain cylinder'havingsquared ends,

a smooth outer periphery and a longitudinal bore 2, a series of separatesections 3 curved transversely to conform to the outer periphery of saidbody, and having radial meeting edges in contact, each of said sectionshaving a connecting series of projections 4 upon its outer surfaceforming a determinate portion of a. definite design in relief, and eachsection having .anintegral flange 5 in the formof a segment at eachterminal. thereof, the same projecting beyond theouter surface of thesection. which carriesit and unitingw-ith the flange of adjacentsections toform complete annular terminal flanges, a spindle engagingthe bore of said body, and a suitable handle applied to said spindle,substantially as here- .in specified.

2. The combination, ina tool for marking artificial stone, of a mainbody or roller .carrying designs in relief upon its outer periphery, andhaving a longitudinal-bore 2, a spin-- vdle 6 mountedin said bore andhaving its ends squared and provided with a threaded bore 7, screws 8having threads upon their inner portions and the plain outersurface,andengaging said bores 7 of said spindle, a U-shaped yoke
